CCPM & Feeder Buffers | | Critical Chain |

[...] the network of tasks that form the longest chain is now the critical chain, but there are other solutions that can assist with task chains that are not on the critical network. These are called feeder chains and the buffers that are created from their 50% confidence factor (CF) reductions are placed at the end of these chains BEFORE they rejoin the critical chain.
